 Cornwall to Sutherland ; while tlie continental distribution is equally wide. 

 Europe, northern Asia to Amur and Japan {Ris). In the south of Europe 

 (Iberian Peninsula, &c.) it is represented by the form mcridioivalis De Selys.

Locally common, frequenting wooded river-banks, especially in the south 

 of Ireland. At Ballyhyland Mr. Moflat says it is totally unknown in most 

 seasons ; but in July, 1889, it appeared in great profusion in the valley of the 

 Urrin, where for the time being it quite outnumbered the common C virgo. 

 It lasted for about a month, and has not been seen in the district since that 

 year.

 observed north of Yorkshire {Lucas, 1900). Widely distributed in the 

 Palaearctic region from Scandinavia and Finland (Nurmijarvi-See) to Algeria; 

 Asia Minor, Turkestan, and Siberia. Replaced in the extreme south of 

 Europe by the race .mnihcstoma (Charp.).
